because they are not able to carry out life process outside the human body they are active only in human body.
Viruses are considered nonliving because they lack cellular structure and do not possess the machinery necessary for metabolism or reproduction on their own. While they do contain proteins, they cannot replicate or carry out metabolic processes without invading a host cell. This dependency on a host for reproduction and their inability to sustain life independently are key reasons why viruses are classified as nonliving entities.
Viruses are considered nonliving because they cannot carry out essential life processes on their own, such as metabolism or reproduction. They lack the machinery to generate energy or replicate their genetic material without a host cell. This dependency on a host for survival blurs the line between living and nonliving entities.
Virus: is a strand of hereditary material surrounded by a protein coating that can infect and multiply in a host cell. Host Cell: a living cell invaded by or capable of being invaded by an infectious agent.
One exception to the characteristic of life is viruses. Viruses are considered non-living because they cannot carry out the basic functions of life on their own and require a host cell to replicate.
they can only reproduce in a host cell

Viruses can not replicate without a living host cell. This is one reason that they are not considered to be alive.

Viruses are nonliving and that fact makes it hard for us to come up with antivirals.
A nonliving specimen refers to something that was never alive, like a rock or a chair. A specimen that is considered dead was once living but has now ceased all life processes.
According to many scientific literature, all living organisms should be able to reproduce.Viruses do not reproduce. Instead, they inject their genetic material into another cell. This process is called pilus.
Viruses are considered to be a serious threat to humans because they are very difficult to control. Very few things can control viruses except antivirals.

it can move
If by non-living you mean an object such as a sheet of metal then no they are not composed of cells. If you are referring to something dead, then yes the DNA is still intact at least for a while anyway they do deteriorate in time.
viruses, in the first place, are non living. when they enter a substrate (e.g. host), that's the time they exhibit actions and processes pertaining to a living organism. this is also the reason why putting viruses in the classification system is still on debate.
